Fence Installation Permits in Olathe

Local Rule

City of Olathe Development Services; Olathe Municipal Code

Olathe exempts fences not over 7 feet in height from a building permit; pool enclosures are an exception and always need a permit regardless of fence height. Zoning under UDO Section 18.50.050 caps fences, walls, or hedges at 6 feet in residential districts; in front or corner side yards beyond the front of the house, fences are limited to 4 feet, must be at least 50 percent open, and cannot be chain-link or other metal/wire fencing. Retaining walls are permitted where reasonably necessary due to topography, set back at least 2 feet from any street right-of-way, and any retaining wall over 3 feet must have fencing. Fences, walls, or hedges are not allowed in the street-right-of-way setback area, and along arterials they are allowed only when approved as part of a master fence/screening plan.

How This Compares to Johnson County

Olathe's own rule is shown above (No permit under 7 sqft). Here is the separate rule that applies at the county level, for context:

Johnson County Planning, Housing and Community Development (

In unincorporated Johnson County, a building permit is not required for a fence unless it exceeds 7 feet in height. Fences under that height must still meet the setback requirements enforced by the county Planning Department. Properties inside any of the county's cities, including Overland Park and Lenexa, follow that city's own fence ordinance instead, and several cities set a lower threshold than the county.
